Cortical-Basal Ganglia-Cerebellar Networks in Unilateral Vocal Fold Paralysis: A Pilot Study.

Objectives/hypothesis: To evaluate differences in cortical-basal ganglia-cerebellar functional connectivity between treated unilateral vocal fold paralysis (UVFP) and healthy control cohorts using resting-state functional magnetic resonance imaging (RS-fMRI).

Study Design: Cross-sectional.

Methods: Ten UVFP study patients treated by type I thyroplasty and 12 control subjects underwent RS-fMRI on a 3-Tesla scanner to evaluate differences in functional connectivity of whole-brain networks.

Cortical networks for speech motor control in unilateral vocal fold paralysis.

Objective: To evaluate brain networks for motor control of voice production in patients with treated unilateral vocal fold paralysis (UVFP).

Study Design: Cross-sectional comparison.

Methods: Nine UVFP patients treated by type I thyroplasty, and 11 control subjects were compared using magnetoencephalographic imaging to measure beta band (12-30 Hz) neural oscillations during voice production with perturbation of pitch feedback.

Vocal motor control and central auditory impairments in unilateral vocal fold paralysis.

Objectives: To evaluate differences in vocal motor control and central auditory processing between treated unilateral vocal fold paralysis (UVFP) and healthy control cohorts.

Study Design: Cross-sectional.

Methods: Ten UVFP study patients treated by type I thyroplasty with stable voices were compared to 12 control subjects for vocal motor control using a pitch perturbation response task and central auditory processing performance using a battery of complex sound intelligibility assays that included adverse temporal and noise conditions.
